Term
Verapamil- MOA & Indications
Definition
Blocks Ca channels on VSM of arteries
*Vasodilation of peripheral arteries- decreased arterial pressure
*vasodilation of coronary arteries
Blocks ca channels in heart
*decreased HR, force of contraction and conduction
Indirect Effect
No change unless underlying cardiac disease
Indicated for: Angina, HT, dysrhythmias (supraventricular), migraine prophylaxis
Term

Definition
Consipation- most common
Vasodilation- dizziness, edema, etc
Gingival hyperplasia
Cardiac effects (high dose or predisposing factors)
Heart Block
Bradycardia

MOA similar to verapamil, but less potent effects on heart
ADR's similar but less incidence
Term
Nifedipine- MOA & Indications
Definition
Calcium Channel blocker
Blocks Ca channel in arterial VSM, activates baroreceptor reflex -> vasodilation
*decreases BP, increased HR and contractile force
Indications- Angina, HT
Term
Nifedipine- ADR's/metabolism
Definition
